How Many Solar Panels And Batteries Do I Need?

Are you presently considering adding a solar system to your home? With several homeowners in the UK using solar now, many more are realizing the numerous benefits they stand to derive by getting one. Therefore, if you’re thinking about adding the system to your home but do not know where to start, you’ve come to the right place.

Here, we’ll help you calculate the number of solar panels and batteries you’ll need to power your home. Starting from the panels, you can begin by taken into account everything that makes use of power in your home to get a good idea of how many you’ll need.

• Firstly, you’ll have to determine the number of watts you use. Simply go through your utility bill for kilowatt-hours (kWh). This varies amongst homes and being able to identify your daily average energy usage will assist you in getting your solar needs.

• Secondly, you have to determine the peak sunlight hours - having in mind that the solar panels only work when under direct sunlight. Once determined, you can then multiply the figure in hours by your home’s hourly energy usage and divide by your selected solar panel’s wattage.

Generally for a 1500 square foot house, you might need around 15 to 18 solar panels to cover the house’s electricity.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries you’ll need for your house. These factors include your home’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications. Once done, you’ll be able to calculate the number of batteries required by your home.

Solar thermal panels work by capturing heat directly from the sun and using it to heat water. This hot water is then passed through a coil to heat the water for your central heating system. Solar thermal systems are compatible with many existing conventional boilers with hot water tanks, and can be set up to feed in to your existing heating system.

Unlike the photovoltaic (PV) power which works to turn a part of the electromagnetic radiation of the sun directly to electrons and electricity, a solar thermal can simply be referred to as the absorption of the sun’s heat for human use. As a result, the solar thermal has a wider range of uses than the PV does in several ways. This is due to the fact that the sun’s heat can be absorbed and transported via a medium and the stored energy incorporated for several great purposes such as to heat water, to heat and cool a home or living space, to prepare a meal as well as to generate electricity. All these functions are useful for both residential and commercial spaces.

There are generally three different ranges of solar thermal energy that are being used which includes the low temperature ( for heating, cooling as well as ventilation), the mid temperature ( used for preparing meals, heating hot water and the likes) as well as the high temperature ( used for generating electricity). To focus more on generating electricity, there are a wide array of ways through which the sun’s heat can be directed at creating electricity via a heat exchanger which operates to super heat water or inert gas to power an electricity- generating plant or to produce electricity via a Stirling engine.

In order to increase their output or make them more efficient, evacuated glass tubes are used to encircle the tubes which in turn helps them to collect more heat energy while also protecting them from re-radiating the heat energy absorbed. The trough are normal positioned north to south as well as to keep tabs on the travels of the sun throughout the day.

If you possess an electric vehicle, then you should be well aware of how expensive the cost of getting electric vehicle chargers can be. The portable charger happens to be one of the most costly chargers that’s present in the market today. As a result, many individuals wonder exactly why ev chargers cost so much. After all, its just a little box with some wiring, so why should it cost up to hundreds of pound or a grand plus another grand or thereabouts for installation. In this post, we’ll give you insights to some of the primary reasons why ev chargers are relatively expensive when compared to other charges. Let’s take a look!

• Production factors. The manufacturing and testing phase alone is actually one of the costliest aspects in building a high quality and reliable charger. As stated by one manufacturer, the cost required to make metallic materials to trip switches to the testing phase and the marketing efforts, can all run up to over £30,000. As a result of this high production cost, the average of a new ev charger can be between  £125 to about £300 depending on whether you need a type 1 or type 2 charger as well as the size required.
• Specific design. If you own an ev, you’d know that there’s a standard charging port which allows for easy charging just like in petrol or diesel powered vehicles. The goal is to design a universal charging port whereby all electric vehicles can charge sufficiently.
• Safety. The development of a electrical design involves a lot of engineering which are quite pricey. However, this is a top priority to ensure the safety of both the user and car.

Unlike in houses built in the 1970s where a good majority of the houses will not need to be rewired, for houses built in the 1960s you’d probably need to rewire the entire house unless the wiring is the modern PVCu coated type. Generally, the homes built especially in the 1960s and 1970s brought about enormous changes. This is because over the years our way of living began to change and as a result, our need for electricity became even greater. In response to this, the electrical systems we incorporate needed to change in order to match the new set standards.

In the 1960s, the amperage normally used was increased to 100, which enables home and property owners to power their dishwasher, microwave as well as refrigerator all on one circuit. However, while this may be a remarkable improvement for our grand parents, this is just enough to cater for our modern day appliances. In recent times, new homes are constructed using a wide range of dedicated circuits due to the fact that each of our appliances makes use of much more electricity to function. Consequently because the 100 amp panels of the 1960s possessed restricted space for breakers, home and property owners who still had the units in their homes will inevitably require a sub panel or a new panel entirely - meaning a total rewiring of their property.

Furthermore in the 1960s, builders turned to aluminium from the previously used copper as it was a great conductor and also happens to be relatively cheap. However, after a couple of years a host of electrical fires cropped up in houses that are wired using aluminium. It was later discovered that when the switch to aluminium was made, the light switches or receptacles which were originally made for the previously used copper was overlooked. It was learned that there’s a corrosive chemical reaction that arises as a result of the two dissimilar metals when connected. Hence, the more reason why aluminium wired houses in the 1960s needs to be rewired.

There’s a need to ensure that all the paperwork are in place,before putting your house up for sale on the property market. An very good example of such essential document is the Electrical Installation Certificate (EIC) which is used as a proof to attest to the fact that the electrical installation works carried out on the property in question was actually done and also whether or not it satisfies the building regulations. It’ll be a contravention of the law to put your house up for sale or actually sell it without producing this important document. Therefore, if you’re looking to sell your house you may wish to know the electrical documentations you need to complete the task. In this post, we aim to provide you an in depth insight into the electrical certificates needed to sell your house while also helping you make informed decisions along the process. Let’s take a look!

You’ll need to obtain two certificates in the event whereby the electrical work done was performed by a registered and qualified electrician. The two documents include:

• The Building Regulations Compliance Certificate - This is provided to confirm that the electrical works done complies with the Building regulations.
• The Electrical Installation Certificate (EIC), alternatively you can have a Minor Electrical Installation Works Certificate which is provided to confirm that the electrical works done satisfies the BS 7671.

In addition, the local building control body must be provided with a copy of these documents. In such an event whereby the electrical work was completed after 2013 and either it was done by yourself or by an individual who isn’t a registered professional, then there’s a need to make sure that work is inspected by a registered third party certifier within 5 days of completion. If the work is found to be satisfactory, you’ll be issued a copy of an Electrical Installation Condition Report.

If you’re considering getting a solar thermal system, one of the first things that comes to mind is the possibility of the system functioning properly during the cold months. The short and simple answer to this question is yes, a solar thermal system works in the winter. However, the downside here is that it’ll be a lot less efficient when compared to how it operates during the warmer months or summer. As a result of this fact, you’ll likely need to rely more on your boiler, immersion heater or any other backup heating system during this period as your solar thermal system will fail to contribute as much as it does during the warmer months. So what exactly is the reason why solar thermal is less effective and less efficient in the winter period? Let’s have a look!

As you know, solar thermal system banks on the sun’s energy to heat the water for your home’s use. During the cold months or winter, the sunlight becomes a lot less available when compared to the warmer months, as a result, there’s less sunlight that’s available to be used for its solar energy. And even more so at the periods when the days are shorter or skies are clearly overcast.

Also having a great impact on a solar thermal system’s output is heavy snow. Flat plate collectors normally have the capacity to cope better during snowy conditions as the light that’s able to travel through the snow will heat up the absorber plate - thereby making the snow slide off more quickly. However, the case is contrary with evacuated tube collectors which possesses a form of vacuum insulation that’s crafted to minimize the loss of heat, meaning they can’t generate heat to melt and cause the snow to slide off in a similar way.
